PAS Battery Runtime Explained

Battery runtime is estimated from usable watt-hours divided by average power, then verified against route and duty-cycle testing.

Quick answer

Estimate nominal battery energy as voltage × amp-hours. Multiply by usable capacity and system-efficiency factors, then divide usable watt-hours by average electrical power. The result is approximate because route, payload, acceleration frequency, temperature, battery age and controller limits change real consumption.

Key facts

01
Amp-hours alone cannot compare batteries of different voltage.
02
Average power over the duty cycle matters more than one peak value for runtime.
03
Voltage sag and BMS limits can end operation before nominal energy is consumed.

Energy calculation

Nominal energy is V × Ah. If a 24 V pack is rated 20 Ah, its nominal energy is 480 Wh; this arithmetic does not state how much is safely usable. Apply documented capacity and efficiency factors.

Duty-cycle calculation

Average power should include powered travel, starts, idle electronics and losses over a representative shift. Runtime hours ≈ usable Wh ÷ average W.

Verification

Repeat the route at realistic payload and battery temperature. Record delivered energy, voltage, current, stop condition and time. Do not publish a HAION runtime claim without an approved test record.
